The Startup Repair feature on Windows 7 and 8 can execute these commands, so use fixmbr and fixboot only when you need to run other commands on the Command Prompt.

To check if Windows is having software problems, start Windows in safe mode by pressing the F8 button on the keyboard while Windows is loading. In this mode, Windows will not use the usual drivers and will not run software that is set to start with Windows.
